Raylar Inc.'s "Cool Gap" manifold is engineered to maximize the horsepower and torque levels of the 496-8.1 engine in high performance use with our "BigPower" aluminum cylinder heads and camshafts. The stock manifold was designed for low RPM and emissions use, and even with expensive modifications cannot meet the higher air flow demands of this engine in performance use. The "Cool Gap" manifold is the best answer to the 496-8.1 engine's intake manifold breathing problems. This new manifold incorporates long high velocity runners to provide excellent low and mid range torque levels and a large volume plenum to satisfy this engine's demand for more air at higher RPM's.

The "Cool Gap" manifold gets its name from two air gaps: one between the engine lifter valley and the manifold runners and one between the runners and the plenum. These keep the incoming air fuel mixtures cool and dense, additionally producing more power and torque over the entire RPM band.

The "Cool Gap" also features a design that allows it to bolt on in the same space as the stock manifold, and accepts all standard fittings, sensors, brackets, injectors, fuel rails, and accessories without additional modifications to the engine or its wiring.
This manifold is more of Raylar Inc.'s "keep it simple engineering" designed to make our products simple to install, lower in cost and easier for our customers to take advantage of the added power and torque of this engine.
Keep "Cool"--Get the Raylar Inc. "Cool Gap" manifold and enjoy the added power of your engine today.
